Description
Technical Field

[0002] In existing technologies, to meet the support and strength requirements of the bottom of carbonated bottles, the bottom of carbonated bottles has alternating valleys and ridges. However, the current design of cooling channels in the bottom mold of carbonated bottles is limited by machining and is generally within a conical space. It fails to flexibly follow the trend of the inner forming surface of the bottom mold and extend undulatingly, resulting in uneven distances between the cooling channels and the inner forming surface. Specifically, the cooling channels are closer to the valleys of the inner forming surface and farther from the ridges. The cooling effect of the cooling channels on the inner forming surface is uneven, which directly leads to uneven temperature distribution of the bottom mold of the carbonated bottle, and thus affects the forming effect of the carbonated bottle.

When there is only one water outlet connecting channel 27, the cross-sectional area of the water outlet connecting channel 27 is equal to the cross-sectional area of the water outlet channel 28. When there are multiple water outlet connecting channels 27, the sum of the cross-sectional areas of the multiple water outlet connecting channels 27 is equal to the cross-sectional area of the water outlet channel 28. By setting the cross-sectional area of the water outlet connecting channel 27 to correspond with the cross-sectional area of the water outlet channel 28, it is convenient to determine the cross-sectional area of the water outlet connecting channel 27.
[0072] It should be noted that the cross-sectional areas of the inlet channel 21 and the outlet channel 28 are fixed.
